Description
図1は、一例として、従来技術による振動供給装置1を概略的に示しており、該装置1は、ベアリング構造体、この実施例では、弾性脚部、即ち、支持部材3a及び3bを介して地面2に設けられている。支持構造体5用の駆動ユニット4が示されており、支持構造体5の上には、この実施例では、供給トレイ6として構成された供給要素が配置され、供給トレイ6の後端部8aに、充填通路7を介して、バルク材料9(例えば、シリアル、医薬品、プラスチック粉及びあらゆる種類の粉体又はあらゆる種類の金属粉体等)が供給される。支持構造体5の振動運動により、供給トレイ6も振動し、その結果、バルク材料9は、供給トレイ6の前端8bで振動供給装置1から排出される。 FIG. 1 schematically illustrates a vibration supply device 1 according to the prior art as an example, the device 1 via a bearing structure, in this embodiment, elastic legs, ie, support members 3a and 3b. It is provided on the ground 2. A drive unit 4 for the support structure 5 is shown, on which the supply element configured as the supply tray 6 in this embodiment is arranged and the rear end portion 8a of the supply tray 6 is arranged. Bulk material 9 (eg, cereals, pharmaceuticals, plastic powders and all kinds of powders or all kinds of metal powders, etc.) is supplied through the filling passage 7. Due to the vibrating motion of the support structure 5, the supply tray 6 also vibrates, and as a result, the bulk material 9 is discharged from the vibration supply device 1 at the front end 8b of the supply tray 6.
ライン19を介して、前記センサで検知された支持構造体の移動は、地面2に配置された制御装置20に伝達され、制御装置は、供給線21を介して交流電流を振動駆動装置10に供給し、支持構造体5の実際の振動運動が、可能な限り、それぞれの送り動作に対して設定された個々の値の範囲内に維持される。好ましくは、振動駆動装置10、センサ16及びライン19,20は、防爆及び電磁両立性を有するように遮蔽され、制御装置は、ライン制御装置と同じ位置に設けられる。 The movement of the support structure detected by the sensor is transmitted to the control device 20 arranged on the ground 2 via the line 19, and the control device transmits an alternating current to the vibration drive device 10 via the supply line 21. The actual vibrational motion of the feed and support structure 5 is maintained, wherever possible, within the range of individual values set for each feed motion. Preferably, the vibration drive device 10, the sensor 16 and the lines 19 and 20 are shielded so as to have explosion-proof and electromagnetic compatibility, and the control device is provided at the same position as the line control device.
(上述した場合のように)支持構造体5が、地面2に堅固に固定されていない場合、それは、駆動された支持構造体5の反力のために、それらと反対の方向にも振動する。従って、センサは、駆動ユニット4と支持構造体5との間の相対変移のみを検知し、地面2における質量流量mに関する重要な変移は検知しない。従って、たとえ、駆動ユニット4の(カウンター)振動の振幅が比較的小さくなるように、駆動ユニット4の質量mAが、例えば、重量で、支持構造体5の質量と比較して大きく維持されていたとしても、質量流量mの調整量の近似値にしかなり得ない、動作中に検出された支持構造体5の振動運動に対して推定補正係数を使用する必要がある。 If the support structure 5 is not firmly anchored to the ground 2 (as in the case described above), it will also oscillate in the opposite direction due to the reaction force of the driven support structure 5. .. Therefore, the sensor detects only the relative shift between the drive unit 4 and the support structure 5, and does not detect a significant shift with respect to the mass flow rate m on the ground 2. Therefore, even if, as the amplitude of the (counter) vibration of the drive unit 4 is relatively small, the mass m A of the drive unit 4, for example, by weight, is maintained larger than the mass of the support structure 5 Even if it is, it is necessary to use an estimated correction coefficient for the vibration motion of the support structure 5 detected during operation, which can only be an approximate value of the adjustment amount of the mass flow rate m.
図4は、本発明に従って、支持構造体5の絶対振幅Aabs T、即ち、駆動ユニット4だけでなく、地面2に対するその変移を調整するための本発明による第二調整サイクルの処理を示している。 FIG. 4 shows the processing of the absolute amplitude Abs T of the support structure 5, i.e., the second adjustment cycle according to the invention for adjusting its transition not only to the drive unit 4 but also to the ground 2 according to the present invention. There is.
以下の表示が関係する変数に使用されている。
「A」は駆動ユニット4を表し、「T」は支持構造体5を表し、「abs」は振幅の絶対値(即ち、振動供給装置自体の構成要素に関するものではなく、地面2に関する振幅の絶対値)を表す。また、「ist」は振動供給装置の動作中の実際の値を表し、「res」は共振を表す。
The following display is used for related variables.
"A" represents the drive unit 4, "T" represents the support structure 5, and "abs" is the absolute value of the amplitude (ie, not the component of the vibration feeder itself, but the absolute amplitude with respect to the ground 2). Value). Further, "ist" represents an actual value during operation of the vibration supply device, and "res" represents resonance.
